4. ELECTRICAL SYSTEM A D CO ECTIO RULES
1. The boiler room should be equipped with a 230V/ 0Hz electrical system, according to the
applicable regulations.
2. The electrical system (regardless of its type) should be terminated with a connection outlet fitted
with a protective terminal. Use of an outlet without a protective terminal causes electrical shock
hazard!!!
3. Connect the Controller to a separately installed power line protected with a properly selected
quick circuit-breaker or a residual-current device (RCD breaker). Do not connect any other devices
to this line!!!
THE CONTROLLER IS POWERED FROM 230V/50HZ MAINS
ANY REPAIRS MAY BE CARRIED OUT ONLY WITH POWER SUPPLY
CUT OFF AT THE FUSE

5. QUICK START
To quickly start the GH10TA Controller, perform the following actions:
1. Touch keyboard calibration.
After connecting the controller to the power supply, the controller for about 4 seconds calibrates the
touch keyboard. During calibration you can not bring your hands to the sensors, because it would cause
incorrect calibration, and consequently malfunction of the keyboard. After calibration process, the device
performs a 3-second start sequence, during which it displays various information, including the firmware
version. When the start sequence is complete, the controller goes into the STANDBY mode. If the keyboard
does not work correctly, you should repeat the calibration process. To do this, disconnect controllers and
then connect the controller to a power supply and calibrate the keyboard touch one more time,
remembering not to put your hands to the sensors..
2. Connect the device to the 230V AC power system (put the plug in the power outlet).

6.7. Boiler Bur out Detectio
6.7.1. No Fuel
If during automatic operation the boiler outlet water temperature remains below the F08 setting
for a period of time set in the F09 setting, then the Controller considers the boiler as “burned out” and
enters the AL13 alarm condition.
6.7.2. Sudden Drop of Outlet Water Temperature
If during automatic operation the boiler outlet water temperature drops by 10°C, and during that
dropping period the temperature does not rise by 4°C, then the CH and HUW pumps are switched off, and
the Controller goes into the burnout detection mode.
The Controller waits for the period of time set in the F10 setting, during which it checks whether a rise of
4°C occurs.
If YES, then the burnout detection condition is stopped, and the CH and HUW pumps (if necessary) are
started.
If NOT, this means that the furnace is burned out – the Controller enters the AL13 alarm condition.
6.8. Maximum Feeder Temperature Detectio
The GH10TA Controller is equipped with an additional option of protecting from temperature rise in the
fuel feeder above the permissible value to prevent backfires into the fuel feeder.
The detection is active only in the automatic boiler operation mode (AUTO, MAINTAIN).
When the measured temperature exceeds the value set in the F14 service setting, the fuel feeder activates
for the period of time set in the F16 service setting to eject the ignited fuel from the feeder. During the F16
period the fan remains stopped.
When the time set in F15 service setting elapses, the Controller restores the maximum feeder temperature
detection process.
When the feeder T > 90°C, then fan is stopped, the fuel feeder is started for a period of 2xF16, and the
display indicates the alarm condition AL11 – “Maxi u feeder te perature exceeded”. (⇒ section 6.
page 11).
The Controller remains in the alarm condition until user response.
IF F14=0, THEN FEEDER SENSOR OPERATION IS OFF AND THE FUNCTION
OF FEEDER MAX. TEMPERATURE INCREASE DETECTION IS NOT ACTIVE.

8.3. HUW Priority
The GH10TA Controller allows to set operation of the HUW pump with priority. If you choose this mode
of HUW pump operation, the hot utility water heating is a higher priority function in the Controller.
To do this, set the F00 service setting to the value of “3”.
8.4. Summer Mode
The GH10TA Controller is equipped with a SUMMER MODE option that allows you to turn off the CH
pump for the summer season, and the boiler operates only to supply the HUW water. To do this, set the
F00 service setting to the value of “4”.
9. ROOM THERMOSTAT
The GH10TA controller can cooperate with external room thermostat (⇒ Fig.1), which can put coal boiler in
blockade position when temperature is reached in room.
During blockade position C.H. pump stay off after 4 minutes, for the moment when temperature in
room is reached (short circuit contact). The boiler start working in maintain operation mode.
The controller GH10TA passing from automatic operation to maintain operation mode just from time to
time, when the boiler temperature is higher than minimum temperature adjust in F03 service parameter or
when HUW circulation require automatic operation controller ( it depend of HUW Priority).
When room thermostat put controller in blockade position, the boiler is in maintain operation mode and
boiler temperature fall down less than F03 service parameter or HUW circulation need heating, than the
controller come back to automatic operation mode until both conditions will be accomplish.
The controller supports the room panel of our manufacture. The controller responses to the panel orders if
the controller is under the automatic operation mode. Where the malfunction occurs to the connection
with the panel, the controller will resume the operation with the user programmed settings.

10. TEMPERATURE LIMITER (STB)
The GH10TA Controller can be equipped with an additional independent temperature limiter STB
via terminals 1 and 16.
WHEN THE TEMPERATURE LIMITER IS NOT USED,
TERMINALS 15 AND 16 SHOULD BE SHORTED.
If due to boiler temperature rise the temperature limiter is activated and opens its terminals, it will disable
feeder and fan power supply in order to stop fuel and air delivery do the boiler. After approximately s
from limiter activation the Controller indicates the AL1 alarm.
Return to normal boiler operation is possible when the boiler temperature drops to a level enabling limiter
reset (temperature level depends on the limiter model used).
For safety reasons the Controller does not resume automatic operation on its own.
For the Controller to resume operation you have to, after resetting the limiter, press twice:
– pressing for the first time cancels the alarm and disables the Controller,
– pressing for the second time reactivates the Controller,
– pressing causes the Controller to switch to automatic operation mode.
